Each fall, about thousands of hawks, eagles, and other birds of prey fly hundreds of miles
in search of warmer climates. And between August and December, nearly 70-thousand
people will climb to the top of a bird sanctuary called Hawk Mountain to get a closer
look at those birds. The Great Lakes Radio Consortium’s Brad Linder reports:


“Those of you haven’t found the osprey, it’s over there at owl’s head, naked eye here to
the right.”


On a clear day, the view from atop Hawk Mountain stretches for more than fifty miles.
But on this particularly hazy Saturday afternoon, bird-watchers are pushing their
binoculars and telescopes to the limits.


“Well, we’re making them out there, they’re coming in. It’s like you just gotta wait ’til
they get a little closer than what they typically do. They’ve been popping out of clouds
and haze all day for us.”


Doug Wood is a volunteer at Hawk Mountain in Eastern Pennsylvania. This afternoon,
he’s the official bird counter.


“We’re basically taking a lot of field information. Wind, weather, temperature, cloud
cover, wind direction. And then we’re basically monitoring the birds’ species, age, sex,
and recording it every hour.


“Look! An Osprey! And then fade to scene change.”


Researchers at Hawk Mountain have been keeping records of osprey and other migratory
raptors for more than seventy years, making it the oldest monitoring station in the world.


In the early twentieth century, hunters would shoot thousands of birds from the
mountainside each year. Today, people travel from all over the world to shoot birds with
their cameras.


Matt Wong came all the way from New Zealand to study at the sanctuary.


“Hawk Mountain is internationally renowned as a hawk watch site. And also a place
where big research actually happens. Now, not many of the locals around Pennsylvania
actually realize this, but it’s actually huge on the international scene. It’s world
recognized, and that’s one of the reasons why I came here.”


In Wong’s country, there are only two species of raptors. In America, he’s had a chance
to study dozens of varieties.


But even with so many different species populating North America, many people still
think of them as strangers or sometimes even as monsters.


“I still get, amazingly to me, a lot of people that think that these birds are out to get us.”


Volunteer Bob Owens has spent the last 20 years doing education programs at Hawk
Mountain.


“If you intrude into their territory when they have young in the nest, or something like
that, yeah, they’re probably going to chase you. As far as them killing babies and taking
them from baby carriages, this is all old wives tales. This just does not happen.”


Owens runs a small farm for a living, where he says hawks and barn owls help keep
rodents under control. But in a larger sense, Owens says there’s a lot people can learn
from these birds.


“Any three and a half pound bird that can apply four hundred pounds of pressure with its
talons is built to do what they’re doing. They are at the top of the food chain. And that’s
the other big thing that it shows us. It just opens up a door here as to all the reasons the
birds are either dropping or rising in population. What are we doing?”


Owens says in the seventy years researchers at Hawk Mountain have been counting birds,
they’ve seen populations rise and fall. Hawks and eagles are hardy birds. But even the
most successful predators can fall victim to environmental change.


Keith Bildstein is the sanctuary’s director of conservation programs. He says raptors are
like sensitive tools, telling researchers when something’s wrong with an ecosystem.


“Birds of prey are excellent biological indicators. In the middle of the last century they
told us that we were having a problem with our misuse of organochlorine pesticides,
specifically DDT. Today, they’re leading us in explorations of the spread of West Nile
Virus.”


Bildstein says because raptors are at the top of the food chain, when their numbers fall
it’s a pretty good sign that their food source is dwindling, their habitat could be
disappearing, or air quality might be suffering.


But for most of Hawk Mountain’s visitors, the birds are more than barometers of a
healthy ecosystem. According to birder Judy Higgs, they’re beautiful creatures,
especially when viewed from a great height.


“These birds are just majestic. And the other thing is that they go so far. You know,
some of these birds are going to South America!”


Higgs first climbed the mountain in 1970, when she was a student at nearby Kutztown
University. Before moving out of state, Higgs used to come to Hawk Mountain daily…
she stills visits on weekends whenever she can.


“I used to do work in the morning, come here in the afternoon, go home, and finish my
work at night so I could be here.”


By day’s end, Higgs and her fellow birdwatchers count more than 600 raptors. During
the fall season, as many as 70-thousand predatory birds, from vultures to falcons might
pass by on their way to distant points.

Earthworms Alter Forest Ecology

Most of us think of earthworms as beneficial creatures. Gardeners are always happy to spot a worm in the flowerbed because they add fertilizer to the soil. Many anglers say they’re the best thing for catching fish. But scientists are beginning to learn worms aren’t so friendly to Great Lakes forests.

Most of us think of earthworms as beneficial creatures. Gardeners are always happy to spot a
worm in the flowerbed because they add fertilizer to the soil. And many anglers say they’re the
best thing for catching fish. But scientists are beginning to learn worms aren’t so friendly to
Great Lakes forests. The Great Lakes Radio Consortium’s Stephanie Hemphill reports.


(fade up Girl Scouts)


This Girl Scout troop is learning about worms. Judy Gibbs is a naturalist at the Hartley Nature
Center in Duluth. She shows the girls how to coax worms out of the soil. They pour water laced
with powdered mustard into the worms’ burrows.


It irritates the worms and they come squiggling up by the hundreds.


“Pour it in. Wait a minute. Here it comes. It doesn’t like the mustard and it comes right up.
Look at this one (laughter). oh, there’s another one. Look at it go!” (shrieks)


On their walk through the woods, the girls look for dead leaves. There aren’t many. Judy Gibbs
explains why.


“Here’s a leaf stem that’s being pulled into this hole. Who’s doing this? Ants! No. Worms.
There’s big night crawlers. You know what a night crawler is? They grow straight down into the
ground, and they come up at night and pull leaves down into their burrows. And they eat the leaf
right off. That’s why we’re not finding any leaves.”


Worms eating leaves might seem natural, but it turns out these worms aren’t native to these
woods. The last glacier buried most of what is now the Great Lakes region. When it melted,
plants and animals returned to create a community of maples, pines, songbirds, and tender plants
growing on the forest floor, like trillium…but not earthworms.


Cindy Hale is a biologist who studies the native wildflowers that grow in northern hardwood
forests. She loves the spring bloomers that take root in the spongy layer of decaying leaves on
the forest floor. Trillium, bloodroot, solomon’s seal.


Hale says many of these plants are disappearing.


“Sites that forty years ago were carpets of trillium have been slowly over the last two decades
declining to almost nothing, and people were scratching their heads, trying to figure out just
what’s going on.”


Earthworm populations are thickest close to cities. But Hale says people bring worms with them
when they come to the woods.


At first, settlers carried them in, along with the animals and plants they brought from Europe or
the east coast. These days, worms are spread by people who drive in the woods – loggers, ATV
riders…


“But in particular, fishing bait is a huge way that worms get moved around in our region.
Because there’s so many lakes and so much fishing.”


Hale and her colleagues set up test plots along an advancing line of worms in the Chippewa
National Forest in central Minnesota. The worms crawl about three yards further into the forest
each year. Hale is studying how the soil and the plants have changed as the worms advance.


Worms eat the decaying leaves on the forest floor. They mix that organic matter into the mineral
soil beneath it. And in time, they can use up all the organic matter and leave only mineral soil
behind.


That means the plants that have evolved to take root in the leaves on top of the soil have lost their
home.


Hale says these changes could affect every plant and animal that lives in the woods. She says,
for instance, even birds have declined by nearly 50% in the last fourteen years.


“Because ovenbirds nest in that forest floor, so if you lose the forest floor, then you may well
affect ground-nesting birds such as that. So when you start thinking about it, the potential
ramifications across the ecosystem get really wild.”


Hale says one of the big challenges in studying this problem is that there’s been very little basic
research – like how many worms are there are and where.


To gather more information and to get more people involved, Hale created a web-based learning
program. She’s asking teachers from around the country to have their classes do worm counts
and other research. Hale plans to add their data to the web page.


In Minnesota, the Department of Natural Resources is working with interest groups to try to slow
the spread of worms. Next year’s fishing regulations will include instructions not to dump your
worms at the end of a day of fishing.

Golf Course Goes Green, Neighbors See Red

Long known for their expanses of shorn grass and highly manicured grounds,
some golf course owners are taking a second look at their landscaping practices and striving to become more environmentally friendly. In the process, however, they seem to have made a few enemies. Great Lakes Radio Consortium commentator Julia King explains:


In a nutshell, here’s the story: Golf Course Goes Green, Neighbors See Red.


Golf course owner Tony Krebs recently saw the environmental “light” and decided to reduce his use of pesticides, gasoline, and water. He wants to mow less, grow wildflowers, re-introduce native grasses and attract wildlife. The neighbors – instead of cheering – have filed formal complaints with the city.


Golf courses have long been havens for precision landscaping, places where the great outdoors are shaped into forms… well, unfamiliar to Mother Nature. So to some residents around golf courses, a new, more natural landscape looks suspiciously like neglect. But it’s not.


For a little over a decade, the Audubon Society has been helping to “green” golf courses with their Audubon Cooperative Sanctuary Program. While any course can become a member and receive environmental tips and guidelines, members earn certification by completing projects in specified areas. Out of an estimated 20,000 golf courses in the U.S., a select 2,300 have achieved certification.


In other words, the movement towards greater sustainability in the golf world is still young. And old standards of beauty die hard. According to an Audubon source, it’s not uncommon for bordering property owners to balk at a golf course’s naturalization. Just as one man’s treasure is another’s trash, apparently one man’s “wildflower” is another man’s “weed.”


But this is more than a beauty-in-the-eye-of-the-beholder tale. Health officials have linked weed killers to everything from childhood leukemia, to gender malformation in frogs. Yet here we have well-to-do citizens banding together to fight for such chemicals.


“We live in a community,” one concerned resident said. “We have to be accountable to one another.” But he was talking about standards of property upkeep, not about public safety or about the delicate ecosystem we share.


He’s right, though, we are accountable to one another. And not only to one another, but to those who come long after we’re gone. There is a price to be paid for that so-called “perfect” landscape, and it’s a price we will all have to pay. It’s time for responsible citizens not only to tolerate sustainability, but to demand it.

Small Wetlands Drowning in Development

  • Small wetlands such as the one pictured above often dry up during the summer. These 'ephemeral wetlands' are home to all kinds of frogs, salamanders, reptiles and aquatic life that depend on this specific kind of habitat for their survival. Photo by Lester Graham.

Biologists are becoming concerned about the disappearance of a habitat for wildlife that can be found in rural areas, in sprawling suburbs, and even in big cities. The Environmental Protection Agency is trying to get city planners, farmers, and developers to stop draining small marshy areas that biologists call ephemeral wetlands. The EPA says in the rush to save big areas of wetlands these small temporary wet spots have been overlooked at the expense of some unique wildlife.

Biologists are becoming concerned about the disappearance of a habitat for wildlife that can be found in rural areas, in sprawling suburbs, and even in big cities. The Environmental Protection Agency is trying to get city planners, farmers, and developers to stop draining small marshy areas that biologists call ephemeral wetlands. The EPA says in the rush to save big areas of wetlands these small temporary wet spots have been overlooked at the expense of some unique wildlife. The Great Lakes Radio Consortium’s Lester Graham has more:

(Frogs sound)

There’s still just a bit of ice along the edges of this little pool, but it’s a warm day, the ice will soon melt, and the frogs sound as if they’re rejoicing. In the coming weeks, this shallow little pond will become a chorus of different kinds of frogs and host a dance of mating salamanders. Many kinds of amphibians and reptiles are drawn to wet spots like this one to mate and reproduce. And. there’s a bit of a rush to their reproductive activities. More than likely by middle or late summer, this little pool will be all dried up. Actually, that’s good because it means fish can’t survive here, fish that would eat the young of many of these species. So a lot of these frogs and salamanders and other creepy-crawly things do really well here while its wet.

Ed Hammer is a biologist with the Environmental Protection Agency. He says these temporary, or ephemeral, wetlands are usually pretty small… most under two acres in size…some so small you could jump across them. But they’re really important to aquatic life such as fairy shrimp and clam shrimp, which can survive, and even need dry periods. And certain species of frogs and other amphibians who use the wetlands for breeding.

(Frogs fade out)

“They’re extremely productive. We have some of these smaller wetlands in our area in the Chicago region that in a quarter acre of size can produce hundreds and hundreds of salamanders and leopard frogs in a good year when the water holds out. They really depend on those habitats being there every few years at the very least.”

And Hammer says the productivity of the ephemeral wetlands helps other species.

“Salamanders and frogs are fed upon by a multitude of other organisms like turtles and snakes and on up the food chain and then, you know, owls will feed on them. Raccoons and skunks and fox and all up the food chain they’ll be fed on. So they’re an extremely important food source.”

The temporary wetlands are also important to many migrating birds such as pintail ducks and little green herons. Paul Zedler is a professor of environmental studies and scientist at the University of Wisconsin arboretum.

“Imagine you’re a bird, a shore bird, looking for habitat in which to forage. Then ephemeral wetlands, while they’re there, can be an excellent place for resting and feeding.”

Zedler says the ephemeral wetlands are amazing to him because of the wet then dry cycle to which so many animals have adapted.

“It’s like instant ecosystem. Like, add water and you get an ecosystem. People who, once it’s pointed out to them, invariably think it’s pretty darn neat.”

But a lot of times, the people who own the ephemeral wetlands don’t realize that area that gets swampy in wet years is a thriving habitat. Ephemeral wetlands are often drained to plant crops, or bulldozed deeper to build storm water retention basins for housing developments, or the surrounding woodlands are cut down eliminating the habitat where many of the frogs and salamanders live the rest of the year.

They’ve disappeared so quickly that some species that depend on ephemeral wetlands are in danger of disappearing too. Gary Casper is with the Milwaukee Public Museum. He’s been studying a certain turtle called Blanding’s turtle to see why its numbers have dwindled so much.

“Blandings turtles look kind of like those old German helmets from World War II and they have a really bright yellow chin and throat with a real long neck. They’re a threatened species in Wisconsin and threatened or endangered in several other states.”

Casper has been watching Blanding’s turtles to see what makes them tick, where they like to live and eat.

“And after looking at the data from seven years of radio tracking, it’s quite clear that they strongly prefer these seasonal, isolated wetlands probably because they provide much more food for them.”

And so they join a host of other critters such as gray tree frogs, marbled salamanders, fishing spiders, wood ducks and others who heavily depend on the ephemeral wetlands.

The EPA is publishing pamphlets and holding seminars to teach state and local officials and those folks interested in preserving wildlife habitat…hoping they’ll spread the word about the value of the seasonal ponds, or mud puddles so that private landowners will keep them around.

Charting a Course for the ‘Big Muddy’

  • A recent National Academy of Sciences report on the Missouri River suggested some of the river's natural meanders and access to the flood plain be restored. It also suggested sections of the river be reviewed to see if barge traffic might be closed for parts of the year or permanently.

The National Academy of Sciences has issued a report that calls for the restoration of the longest river in the United States. That report says the government needs to stop studying problems along the Missouri River and – with the help of residents – do something about them. The Great Lakes Radio Consortium’s Lester Graham has the story:

The National Academy of Sciences has issued a report that calls for the restoration of the longest river in the United States. That report says the government needs to stop studying problems along the Missouri River and – with the help of residents – do something about them. The Great Lakes Radio Consortium’s Lester Graham reports:

On the opposite bank from here, you can see the Big Muddy empty into the Mississippi River. I’m standing on the spot where Lewis and Clark and the Corps of Discovery spent the winter before starting their historic expedition up the Missouri, across the Rockies and to the Pacific coast. If Lewis and Clark could see the Missouri today, there’s little that they’d recognize at this end of the river. Over the years it’s been straightened, walled-in by levees and channelized. Its braided river system of meanders, backwaters and eddies, once alive with wildlife are – for the most part – gone.

Seventy years ago as the government began huge civil engineering projects; it expected the Missouri River to be a major transportation means of getting grain from the farm fields of Nebraska, Kansas, Iowa and Missouri to the markets. But as it’s turned out, almost all of the grain from those states is moved to market by truck or rail or in Missouri’s case on the Mississippi River. Only a tiny fraction less than one-half of one-percent of all the grain harvested in those states is moved by barge on the Missouri River.

According to the Army Corps of Engineers, barge traffic on the Missouri benefits the economy by saving about seven million dollars in transportation costs. But some years the Army Corps of Engineers spends that much maintaining the lower Missouri as a navigable river, and the taxpayers foot the bill.

The National Academy of Sciences – the NAS – was instructed to study the Missouri River and determine the best uses of the river and its flood plain. Stephen Gloss was the chair of the committee that wrote the final report. He says one thing’s certain; the condition of the Missouri River has been studied to death. Its problems are well documented.

“The people should understand the Missouri River ecosystem is in a significant state of decline. There’s been a lot of degradation of the ecological properties of the system. There’s ample scientific evidence to credibly demonstrate that and there doesn’t need to be any more research done to make that credible. The most important thing is to undertake some immediate action.”

The NAS report suggested that the people of the states along the Missouri River should start figuring out where some of the Missouri’s meanders could be replaced and where it could be allowed back into its old flood plain.

At a town hall meeting in Columbia, Missouri, three of the authors of the study, including Stephen Gloss, met recently with representatives of the barge industry, agriculture and government agencies along the Missouri River and with the public. A farmer from Oregon, Missouri, Lanny Meng, told the NAS committee members he’s heard this kind of talk for several years, and he didn’t much like it.

“When they talk about meanders of the Missouri channel and they talk about connectivity with the flood plain. And that flood plain’s my cornfield.”

“Well, I think that the flow change and the management change of the Missouri River’s gonna have a drastic negative affect on my farming practice, and my neighbor’s farming practice and my county. Things will change badly for our community?”

The farmers are not the only ones concerned about change on the Missouri River. The barge industry, which depends on keeping the water level artificially high and the channel deep doesn’t believe there’s enough water to keep the reservoirs full in the upper Missouri, make new diversions for wildlife backwaters and meanders, and keep the barges floating.

Chris Bescia is with the barge industry group Midwest Area River Coalition 2000, better known as MARC-2000.

“So, when the National Academy of Science report says that we want to have more cuts and alluvial deviations in the river, when they say that we want to re-connect the flood plain, when they say all these things, that’s essentially taking out the channel training structures that are designed to maintain a nine foot channel.”

Which the barges need to push their cargo up and down stream.

The NAS report indicates that the people along the river and the state and federal agencies that have authority can find a balance between the commercial and agricultural interests and that of those who want better hunting, fishing, or simply better habitat for the sake of the wildlife and the natural beauty.

Chad Smith is with the environmental group American Rivers. He says it will take some compromises, but it can be done.

“The Missouri is not even close to living up to its potential. And we’re missing out on a lot of quality of life benefits, but also on a lot of economic benefits by managing this river as a ditch and not as a river.”

Smith stresses that no one is calling for the end of barge traffic on the Missouri, or wants the end of farming in the flood plain. But Smith says there’s been just a little too much development of the river, and we need to restore parts of it here and there.

The chief author of the National Academy of Sciences report, Steven Gloss, says that work needs to begin quickly because it will take a very long time to fix the Missouri River’s problems.

“We’ve been at this for a long time, a hundred years or better and, you know, it’s gonna take several decades to get it back a little bit in the other direction. I think we really need to look at this as a long-term sustained process. It’s not something we can find a solution for in five years and walk away from it. We need to be at this for the rest of our lives and for future generations.”

But Gloss stresses this cannot be a job for the government alone. The NAS report says the Missouri can only find balance between the competing interests if the people along the Missouri River all have a seat at the table and share in the river’s wealth.

Sowing Seeds to Restore a Wetland

Lost wetlands are restored for a number of reasons. Sometimes they replace a wetlands area lost somewhere else because of construction or agriculture. But typically these projects are small in scope. Now a conservation group is looking to create an entire ecosystem in the Midwest through a massive wetland restoration program. The plan is garnering attention from scientists as a new model for how to return land to its natural state. The Great Lakes Radio Consortium’s Jonathan Ahl reports.


(Ambient sound – the farm)


Tractors are rolling across the Wilder farm in Central Illinois, tending to fields lined with rows of corn and soybeans. This plot of land is 76-hundrd acres, or nearly twelve square miles. It’s the biggest farm in the entire state. But it won’t be a farm for much longer. The Nature Conservancy has purchased the land, and hopes to make the area one of the biggest Midwest wetland restoration projects ever. The group hopes the Emiquon Wildlife Refuge will make improvements to the land ranging from creating a new stop for migrating birds, to improving the quality of the Illinois River that is the source of drinking water for hundreds of thousands of people. Joy Zedler is an Ecology Professor at the University of Wisconsin. She says the size of this project creates a unique opportunity to reintroduce extinct plants once native to the area.


“If you have a wetland the size of this table, and you want to restore an endangered species, very likely you wont be able to find the right conditions to support it. But if you have 7600 acres, somewhere in that site may well be the combination of conditions that can support that species.”


Zedler says bringing native plants back to the area can provide food and habitat for a variety of animals and insects that were once native to that region, and improve the health of the region’s ecosystem for miles in every. One major advantage Emiquon has is the entire farm is surrounded by a levy. That means one hole in the levy could allow the area to be a contained flood plain for the river. Rip Sparks is a professor at the University of Illinois. He says allowing that to happen has the potential to bring a wide variety of plants and animals back to the river area. That’s because it would create a seasonal flood plain.


“The spring flood lasts long enough that the organisms have adapted to utilize it for spawning and feeding areas. And the birds have used it as feeding areas as they make their migrations. So it seems very important that river be connected to the flood plain.”


But not everyone is excited about the plans to turn Emiquon into a wetland. Tom Edwards is an activist who has studied the Illinois River region for decades. He is one of several environmentalists that say all of the excitement about the project is mis-founded. Edwards says the waters of the nearby Illinois River are so polluted, that if one drop becomes part of the Emiquon site, all the talk of reintroducing native plant and animal species will become moot.


“Nothing on the Illinois River has any vegetation on it. It’s a toxic waste. The fish can hardly survive. If they let the river water in, it will create another mud hole. It’s not a way to cleanse the river, and we would lose a valuable asset for the future.”


Edwards says Emiquon can be a separate, stand alone lake that protects some wildlife and plants. But he says it will never be the grand experiment in wetland restoration that some claim it will be. Many scientists counter Edward’s argument by pointing out that wetlands can be excellent filters for pollutants, and improve the quality of nearby bodies of water. And the Nature Conservancy says it is aware of the challenges of creating a wetland so close to a less than healthy river. And that, says the Conservancy’s Michael Rueter, is what makes this site ideal. Because it’s enclosed by levies, whatever is done here can be reversed. If opening the site to the river causes problems, the levy can simply be closed up again, and something else can be tried.


“Any action that we take will be reversible. So we’re not taking down levies or lowering the heights of levies. Because we want to be able to reverse this and adapt as we learn more information.”


Rueter says one option would be to install a gate in the levy, so they could control the amount of water that comes into Emiquon. Scientists could than closely monitor the effect of adding River water to the site. Reuter says the Nature Conservancy hasn’t decided how it will approach restoring the site just yet. The group has time to think about it. Part of the purchase agreement gives the former owners the right to continue to farm the land for up to five more years. But when it does become a restoration project, it will likely have the attention of activists and researchers around all of the Midwest. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.

What’s an Ecosystem Worth?

A lot of things found in and around the Great Lakes can be bought and sold – from drinking water to lakefront property. Still, some features of the lakes – like its ecosystem – are not for sale.

A lot of things found in and around the Great Lakes can be bought and sold, from drinking water to lakefront property. Still, some features of the lakes — like its ecosystem — are not for sale. The Great Lakes Consortium’s Jim Meadows reports a new study tries to measure the value of something many consider priceless.


The Lake Michigan Federation says there’s no commodity price for healthy fish and birds living around Lake Michigan — but that people are willing to pay to preserve them. A study prepared for the Federation at the University of Illinois at Chicago estimates how much people would pay — the so-called “natural capital” value of the southern Lake Michigan shoreline. Anna Cooper, who worked on the study, says their numbers could play a role in future decisions about the lake. Just one example she gives is the decision in Chicago to close a small airport along the lakeshore. Meigs would be closed, and the land used for other purposes.


“You know, if it could be shown that having that area as a natural preserve or changing it back into a wetland or something like that, if that could be shown to be basically cost-effective, that people … would value those species and that habitat more than they would value that land put to another use.”


The study estimates Chicago area residents are willing to pay 117 to 197 dollars per household to preserve the lakeshore ecosystem – for a total natural capital value of roughly three to five billion dollars per year, but it’s only an estimate. The Lake Michigan Federation’s Joel Brammeier says they couldn’t afford to do an actual survey of residents — so they extrapolated.


“In this study, we employed a technique called benefits transfer, which is the transferring of data from one study with a similar species and situation to a new region, in this case the Chicago region.”


Still, Brammeier says their study is a good conservative estimate of how much Chicagoans value the lakeshore ecosystem, and he believes other parts of the Great Lakes would also benefit from a valuation of their natural capital. For the Great Lakes Radio Consortium, I’m Jim Meadows.

Long Term Impacts of ’93 Flood

The Mississippi River is changing. Some fish and wildlife that once
lived in or around the river are gone and other plants and animals are
moving in. The Great Lakes Radio Consortium’s Lester Graham reports
researchers are finding that the flood of 1993 has accelerated those
changes:

Discovering Impacts of the ’93 Flood

  • Like many other trees that produce food for wildlife, this pecan tree died after the '93 flood.

It’s been more than five years since the great flood of ’93 hit the

moved to higher ground. New levees have been built. And… people —for
the most part— have recovered from the damage. The Great Lakes Radio
Consortium’s Lester Graham reports that researchers are finding the
